The baSe issuppofted on fOUr caSt efs 7, A tTansvefSe bface Shovvn as con1pTisingtvvo Spaced parallel boTS 8 connects two oppositely positioned sideInen1 beTS 5 and secufed by vvelding, of otheTvViSe, to the fop of baSebars 8 iS a plafe 0 fo the uppef Surface of which iS Secufed anelongated beaTing 10 in which iS journaled a Shaft haZing a beve1 geaf11 at one end and a UniveTSal 12 and cTank 13 at the other end. Anotherbevel geaf which has been designed by nunlefal 14 iS pivoted in abearing in plate 9 for fotatiOn abont a vertica1 axiS aS Shovvn nloSfclearly in Figufe 2. AL veftical thfeaded baf of screvv 15 is connectedvvith gear 14 by a coupling nlenlbeT 15- An e1*ongated tubular bearing17 iS supooffed veItically above the gear aSSefnbly Shown in Figure 2and in axial align- Inenf With fhe threaded baf of Scfevv 15, by follrtubLlla1 Support baTS 18 vhoSe lower endS afe welded to fhe coTners ofthe baSe and whoSe upper ends are welded to fhe tUbU- lar bearing, allaS Shown in FiguTe 1. The baSe With toe tubula1 baTS fofInS aTectangulaf pyran1id whose veTteX lS fofIned by beafing 17. The stand iSfufthef strengthened by bTacing struts 19 connected betWeen 01e bracebaTS 8 and the suppoft barS. Slidable and rotatable in beafing 17 is atubula1 Standard 20 Which has attached to its loWef end a nut 21.withwhich screW 15 isfn threaded engageInent. Attached to the npper end ofthe standard 20 is a Work nppoftng oradle coITlpriSing a bottoIn bar 22and ver ffoal SideS 23 fof1ing a wide npwardly opening U-'shapednTeInber. Attached to the upper end of the Standard 20 o foortfiangularwings 24 Which are Spaced angularly degrees. TWo dian1etricalvvings have beaTings 25 in WfI=fchfS jonTnaled a pivot 25 Which iSvvelded to the under Sde of the bar 22.- T-he othe1 pair of Wings arepfovided t theiT ends With thfeaded openings fof adjusting scfows 27Which engage the under side of bar 22 and by In-oanS of Which thecfadlecan be tilted. zttached to tho vorfiC1 Sides 23 of the cradlo feclaniping neIIbefS 20 Which on b e adjusted to engage a transn1issionhouSing poSitioned in the cTadle.
